In this paper we describe some certified algorithms for exact real arithmetic based on co-recursion. Our work is based on previous experiences using redundant digits of base 2 but ...
We present new sound and complete axiomatizations of type equality and subtype inequality for a first-order type language with regular recursive types. The rules are motivated by ...
We develop a control flow analysis for the Imperative Object Calculus. We prove the correctness with respect to two Structural Operational Semantics that differ in minor technical ...
Behavioral rewriting di ers from standard rewriting in taking account of the weaker inference rules of behavioral logic, but it shares much with standard rewriting, including noti...
In this paper we introduce a logic for parametric polymorphism. Just as LCF is a logic for the simply-typed λ-calculus with recursion and arithmetic, our logic is a logic for Sys...
